Letters Patent No. 93,189, dated August 3, 1869.

The Schedule referred to, in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, IsAAc It. FISHER, of Reading, in the county of Berks, and State of Pennsylvania, In ve invented a new and useful Improvement in Gas- Burners; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of thisspeeification.

This invention relates to a new and useful improvement in gas-burners, having especial reference to horizontalbumers; and consists in a device for protecting the. flame of the lighted gas from lateral currents of air when the flame has been turned dowu to its lowest point, so as to retain suiiicient fire to save the trouble of relighting the gas when a full light is re; quired. I

In the accompanying sheet of-drawings Figure 1 represents a longitudinal side view of the burner with my improvement attached.

Figure 2 is a top or plan view of the same.

Similar letters of reference indicate corresponding parts.

A is the burner, which is screwed on tothe gas-fi tture.

B is the stop-cock.

O is a sliding cone on the burner, which hasbecn arranged with the view of protecting the reduced flame of an upright burner.

' This slide is operatedby turning the cock B, which is connected therewith by the rod D and the arm 0, as seen in the drawing.

This arrangement I do not claim.

My invention is used under entirely different circumstances, the slide 0 being for the upright burner only.

In many situations, especially for billiard-rooms, it is necessary to have horizontal instead of upright burners, in order toavoid the shadows cast upon the table by the burners or by the gas-fixtures.

The flame of the horizontal burner is not objection able on that account, and is usually employed.

When the tables are not in use, the lights are turned down to the lowest point of fiame,so that when the gas 'is turned on again, the illumination will be,

complete,- without the necessityof relighting the gas. To render the slide 0 available for the horizontal light, I apply the adjustable cap F.

This cap is semicircular in form, and pivoted to the slide 0, as seen at g' g.

- The circle of the cap corresponds with the outside of the slide, as nearly as may be, and is made somewhat conical, so as to fit in some measure the conical top of the slide. It is connected with the cock B by the, arm h and the rod i, and is operated by the same movement of the cock which actuates the slide 0, and lets onor cuts off the gas.

For the upright burner, the slide is open at the top."

To adaptto the horizontal burner, another apexture is made'on the side, as represented by J, fig. 2.

\Vhen the gas is turned down on the horizontal burner, the cap is turned by the movement or quarter revolution made by the cock, so as to cover the aper ture in the top of the conical slide, and leave the side aperture J open, as seen in the drawing.

When the gas is turned on again, the opening J is closed by the cap, and the aperture in the slide opened, both slide and cap being thrown forward, as seen in the drawing,for the reduced flame, and drawn back entirely from the top of the burner for the full flame.

By this arrangement, the reduced flame of the horizontal burner is screened or protected from lateral currents of air, which would otherwiseextinguish it.

Having thus described my invention,

I claim as new, and desire to secure Patent? In combination with a gas-burner, the cap F, arranged and. operating substantially as and for the purposes herein shown and described.

by Letters The above specification of my invention signed by me, this 10th day of J unc, 1869.

- ISAAC It. FISHER.
